Which motor did you get? Stock or upgrade?

Upgrade from the stock 350/500W motor to the real 750W watt from Bafang

You can just see the stock Rad Motor in the background of the pic

Cool! So you have the torque of a geared motor plus a good top speed. To put that on a City would require a new wheel too right? Due to thickness of the motor.

I have a Rover, 30 minutes work to switch . On a city with a freewheel the rear frame sizing is wrong.

Not an expert but with a city you need a MAC/ GMAC motor.

The new RAD mission has the smaller wheel and the geared hub but it's fixed gear.
